Abstract: Two-standard television receiver for frequency-modulated signals either under PAL or NTSC, or under MAC, with a demodulator device including upstream of the frequency demodulator proper (5) a filter with variable tuning frequency (4) slaved to the frequency of the input signal by means of a feedback returning the demodulated signal output by the demodulator to the tuning-adjustment input of the said filter via, under PAL or NTSC, a first loop including a low-pass filter (7), and a second loop which includes a band-pass filter (9), with an adder (8) for adding the signals output by each of the two loops and applying them to the tuning-adjustment input (13) of the filter. 
<??>According to the invention, the low-pass filter of the first loop is the only phase-shifting element of this loop and, in order to adapt the television to the MAC standard, the device is simply provided with a switch (12) for turning off the second loop. 
<??>Application: satellite television, for demodulation of a signal with intermediate frequency in the 400-700 MHz frequency range, in which signals may equally well appear under the PAL standard as under the MAC standard.

Abstract: This invention is directed to a screening method for the selection of mutations which confer acetohydroxyacid synthase (AHAS) inhibiting herbicide resistance to wheat. After mutagenesis of wheat seeds, the seeds are soaked in an AHAS inhibiting herbicide-containing solution containing a particular class of AHAS inhibiting herbicide. After planting, the soil containing the seeds is sprayed with an AHAS inhibiting herbicide of the same class as that used in the seed soak step prior to the emergence of the seedlings from the soil. Those wheat seedlings which emerge and are normal in appearance demonstrate resistance to the class of AHAS inhibiting herbicides used in the seed soak and spraying steps. This invention is also directed to the wheat selections and seeds identified by the screening method.

Abstract: The magnitude of an amount of correction of unbalance at each axially opposite end face of the rim-fitted tire and the position on a circumference of each of the rim end faces are measured by means of an unbalance measuring machine for simultaneously measuring an amount of correction of static unbalance and an amount of correction of dynamic unbalance. The magnitude of the amount of correction of static unbalance, the position of an amount of correction of static unbalance on a rim periphery for minimizing a magnitude of an amount of correction of residual dynamic unbalance, the magnitude of the amount of correction of residual dynamic unbalance, and the position of the amount of correction of residual dynamic unbalance on the circumference of each of the rim end faces are calculated on the basis of the magnitude of the amount of correction of unbalance and the position of the amount of correction of unbalance on the circumference of each of the rim end faces measured. A balance weight of a magnitude corresponding to the magnitude of the amount of correction of static unbalance is fixed at the calculated position on the rim periphery, and a balance weight of a magnitude corresponding to the magnitude of the amount of correction of residual dynamic unbalance is fixed at the calculated position on the circumference of each of the rim end faces, thereby correcting weight unbalance of the rim-fitted tire.

Abstract: In a method for producing rings consisting of pure graphite films, a graphite film strip is wound concentrically onto the core of a mould and is subsequently compressed in the axial direction. A cut which is oblique or is located parallel to the axial direction is subsequently carried out. During the compression, the graphite film strips are displaced within predetermined limits in the axial and radial directions of the ring which is to be pressed, which leads to a Z-shaped or multiple Z-shaped folding of the layers formed from the graphite film strips. After production of the cut through the pressed ring, the cut ends are preferably drawn apart from one another in the axial direction by an amount which corresponds approximately to the internal diameter of the ring, and the ring is subsequently subjected to a second pressing process. <IMAGE>

Abstract: The invention relates to a filter pipe for dewatering during the compaction of fresh concrete or similar mixtures, especially for the prefabrication of large concrete elements, for example for construction of living accommodation. A control slide pipe (4) is arranged in the filter pipe (3), bears on the inside wall of the filter pipe and can be displaced along the axis of the pipe and can be pulled out through the shuttering (1). By means of the control slide pipes, the sequence and degree of dewatering can be adjusted in sections to the shape of the concrete element. The concrete element receives a very compact, virtually pore-free structure, and therefore a high degree of durability. The shuttering can be partly removed immediately after compaction of the element. <IMAGE>

Abstract: An apparatus and method are provided for use with a system including a digital data base for storing digitized images and digitized audio messages, for controlling concurrent reproduction of digitized images on an image reproduction device and audio information on a sound reproduction device. The digitized images are stored as image data files in the digital data base. Likewise, the digitized audio messages are stored as audio data files in the data base. Audio messages and images are associated with each other. This is accomplished by means of a presentation sequences file stored in the data base or in a separate EEPROM memory. In response to a user command, a controller causes image data and audio data for a selected image and an accompanying audio message to be read from the data base. The respective data are provided to the image reproduction device and the sound reproduction device, respectively, whereby the audio message is played back by the sound reproduction device as the image is displayed on the image reproduction device. A controller maintains the display of the image for the duration of the audio message. The controller reads a sequence of images and audio messages from the data base and displays each image and plays back one or more associated audio messages in turn.

Abstract: A uniform reflectance mirror deflector of an optical scanner for scanning a light beam onto an image object or a receiving medium. The scanner preferably includes a rotatable polygon-shaped mirror having a plurality of planes reflective mirror facets for deflecting and thereby scanning said beam through a predetermined angle while rotating and thereby varying the angle of incidence of the light beam on the deflector. In order to achieve relative uniformity of reflectance and avoid intensity variations in the reflected beam, a protective optical coating layer is selected to have a thickness which minimizes variation in reflectance over the range of angular displacement of the mirror in relation to the light source during its rotation. The thickness of the protective coating layer uniformly applied over the entire surface of each facet of the polygon-shaped mirror is determined by calculating the reflectance of P-polarized and S-polarized incident radiation components at a predetermined wave length of incident radiation over a range of protective coating film thicknesses of between 0 and one wave length and over the range of angles of incidence. Coating thicknesses in this range are selected in accordance with the resulting demonstrated relative uniformity of reflectance.
